## Description and Communication Flow

The Valisys software is a product from Tecnomatix Technologies, Inc. that frequently uses other vendor’s software to provide the actual machine control to operate CMMs. PC-DMIS has the capability to support this mode of operation. Although frequently referred to as the Valisys interface, this should not be confused with an actual machine interface. The connection is between a Valisys host computer and a computer running PC-DMIS. All the logic for supporting this mode is within the main PC-DMIS executable. The various interface DLLs used by the PC-DMIS executable to communicate with CMMs do not contain any logic specific to the Valisys mode.

The connection between Valisys and PC-DMIS can be via either TCP/IP or Serial (RS232) communications. This is completely independent of the method by which PC-DMIS communicates to a particular CMM. The following diagram illustrates the general structure and data flow.

(B) - Serial (RS232) or TCP/IP

(C) - Computer with PC-DMIS

(D) - CMM Specific Interface DLL
